I am confused, sorry:(

so.
Palisades does the playsets. And they are releasing the Mega muppet soon. Who does the diecast cars? and who does the Busts? I want those. I have the lab playset and when i am done moving in to my new place i will be ordering more.

But I am not sure who to contact. Can someone help a stupid person like me please?
thanks
